It's the second one that's correct...
US vs. Nixon was the Supreme Court case that was focused around whether or not Nixon would be forced to release tape recordings and other evidence to federal courts.
In a unanimous decision, the court ruled he must disclose these documents. Essentially, this court ruled that just like other citizens, Nixon is not above the law. When any individual is subpoena for records they must provide them, including the president.
Answer:
In search of fame and fortune, Portuguese explorer Ferdinand Magellan (c. 1480-1521) set out from Spain in 1519 with a fleet of five ships to discover a western sea route to the Spice Islands. En route he discovered what is now known as the Strait of Magellan and became the first European to cross the Pacific Ocean. The voyage was long and dangerous, and only one ship returned home three years later. Although it was laden with valuable spices from the East, only 18 of the fleet’s original crew of 270 returned with the ship. Magellan himself was killed in battle on the voyage, but his ambitious expedition proved that the globe could be circled by sea and that the world was much larger than had previously been imagined.
